Item Automating GDPR Compliance using Policy Integrated Blockchain(2020-01-20) Mahindrakar, Abhishek; Joshi, Karuna; Information Systems; Information SystemsData Protection regulations, like GDPR, mandate security controls to secure Personal Identifiable Information (PII) of the users which they share with service providers. With the volume of shared data reaching exascale proportions, it is challenging to ensure GDPR compliance in real-time. We propose a novel approach that integrates GDPR Ontology with Blockchain to facilitate real-time automated data compliance. Our framework ensures data operation is allowed only when validated by data privacy policies in compliance with privacy rules in GDPR. When a valid transaction takes place the PII data is automatically stored off-chain in a database. Our system, built using Semantic Web and Ethereum Blockchain, includes an access control system that enforces data privacy policy when data is shared with third parties.Item DATA PRIVACY MANAGEMENT USING PRIVACY COMPLIANT BLOCKCHAIN STRUCTURES(2018-01-01) Banerjee, Agniva; Joshi, Karuna Pande; Computer Science and Electrical Engineering; Computer ScienceAn important requirement of any information management system is to protect data and resources against leak or improper modifications, while at the same time ensure data availability to legitimate users. Moreover, systems handling personal data must also track its provenance and be regularly audited to comply with regulations. By assuring auditable, privacy policy compliant actions, we can also guarantee that areas where privacy policies have been technically enforced are highlighted. As part of this theses, we have built a novel framework to automatically track details about how a consumer's private data is stored, used and shared by a Cloud provider. We have created a semantically rich data privacy ontology and integrated it with the properties of blockchain, to develop an automated access-control and audit mechanism that enforces users' data privacy policies when sharing their data across third parties. Our blockchain based data-sharing solution addresses two of the most critical challenges specifically: transaction verification and permissioned data obfuscation. Our solution ensures accountability for data sharing in cloud, by incorporating a secure and efficient system for End-to-End provenance. We concur that decisions regarding the collection, sharing, and use of Personally Identifiable Information (PII) must take into account both ethical and privacy considerations.Item Link before you share: Managing privacy policies through blockchain(IEEE, 2018-01-15) Banerjee, Agniva; Joshi, Karuna PandeWith the advent of numerous online content providers, utilities and applications, each with their own specific version of privacy policies and its associated overhead, it is becoming increasingly difficult for concerned users to manage and track the confidential information that they share with the providers. We have developed a novel framework to automatically track details about how a user's PII is stored, used and shared by the provider. We have integrated our data privacy ontology with the properties of blockchain, to develop an automated access-control and audit mechanism that enforces users' data privacy policies when sharing their data across third parties. We have also validated this framework by implementing a working system LinkShare. In this paper, we describe our framework on detail along with the LinkShare system. Our approach can be adopted by big data users to automatically apply their privacy policy on data operations and track the flow of that data across various stakeholders.
